Voltage, otherwise known as electrical potential difference (denoted ∆V and measured in volts) is the difference in electric potential between two points (adapted from Wikipedia). Voltage can be constant (DC) or varying (AC).

Phase shift between pole voltage and line-to-line voltage (3 phase)
I understand that the pole voltage phase shift is 120degrees for 3 phase and the line to line voltage is equal to the difference in 2 pole voltages. … However, how do I work out the phase shift between a pole voltage (say phase a) and the line to line voltage (vab)?
Thank you. …

V/f ratio for 3 phase induction motor greater than rated speed
I am a bit confused with V/f ratio. I know it is used to control the speed, as the output is constant. However, for an induction motor I was doing an experiment on, the rated V/f ratio was 230V/50Hz w …
